I am currently a Postdoc Research Scientist working with Prof. Cedric Josz at Columbia University. I got my PhD in Data Science from The Chinese University of Hong Kong (Shenzhen) at 2024, under the supervision of Prof. Andre Milzarek . From Sep 2023 to June 2024, I was a research associate at The Hong Kong Polytechnic University (PolyU) working with Prof. Ting Kei Pong. From July 2024 to Sep 2024, I was a research assistant at The University of Hong Kong (HKU) working with Prof. Man-Chung Yue. Previously, I obtained my bachelor degree and master degree in Computational Mathematics both from University of Science and Technology of China at 2017 and 2020, respectively. My Master's advisor is Prof. Ligang Liu. My research interests mainly include nonsmooth optimization, second-order theory, and splitting algorithms. I also did some researches on Computer Graphics.
